基于Q方法的旅游目的地形象偏好结构

采用Q方法,通过收集并分析受访者对不同类型旅游目的地形象的偏好排序,发现其形象间存在兼容性和不相容性,且存在5种典型旅游目的地形象偏好结构,分别是:自然生态旅游偏好型、城市旅游偏好型、自然文化旅游偏好型、漫游体验旅游偏好型和探索冒险旅游偏好型。相似性分析表明:5种偏好类型均不喜欢厚重的文化体验,而偏爱轻松及互动式的文化体验。5种旅游目的地形象偏好结构对应特征明显、区分度高,对于旅游营销及旅游线路的设计具有较高的参考性价值。2017年度国家自然科学基金项目“基于实物期权理论的景区经营权价值评估模型与方法研究”(71774135

Information and Communication Technologies and Informal Scholarly Communication: A Review of the Social Oriented Research

This article reviews and analyzes findings from research on computer mediated informal scholarly communication. Ten empirical research papers, which show the effects and influences of information & communication technologies (ICTs), or the effects of social contexts on ICTs use in informal scholarly communication, were analyzed and compared. Types of ICTs covered in those studies include e-mails, collaboratories, and electronic forums. The review shows that most of the empirical studies examined the ICTs use effects or consequences. Only a few studies examined the social shaping of ICTs and ICT uses in informal scholarly communication. Based on comparisons of the empirical findings this article summarizes the ICT use effects/consequences as identified in the studies into seven categories and discusses their implications

货币政策规则非对称性及其在我国的检验

基于最优货币政策规则的研究框架,本文从非线性总供给曲线和中央银行非对称偏好的角度来阐述货币政策规则中非对称性的理论形成,并利用GMM方法估计和检验了我国货币政策反应函数中的非对称性。研究结果表明非线性总供给曲线可以作为解释我国货币政策非对称反应的一种来源,更重要的是,中央银行对通胀缺口存在负向偏好,且这种负向的通胀偏好可以很好地解释我国"后金融危机时代"的通货膨胀偏差,但对产出缺口的非对称偏好并不显著。此外,不同通胀目标的稳健性研究表明,中央银行都存在负向通胀偏好,而且该负向偏好随着长期通胀目标的降低而逐渐减弱
